Abstract

a chapa de aço da presente invenção tem uma composição química específica e é dotada de uma estrutura representada, em termos de razão de área, por 0 a 30% de ferrita e 70 a 100% de bainita. quando um grão de cristal for definido como uma região que é circundada por contornos de grão com uma desorientação de 15° ou mais e para a qual o diâmetro circular equivalente é 0,3 µm ou mais, a proporção de grãos de cristal que têm uma desorientação intragranular de 5 a 14° em relação a todos os grãos de cristal é 20 a 100%, em termos de razão de área. a densidade numérica de contorno de grão de uma solução sólida de c, ou a densidade numérica de contorno de grão total de uma solução sólida de c e uma solução sólida de b é 1 partícula/nm2 a 4,5 partículas/nm2 inclusive. o tamanho médio de partícula de cementita precipitada nos contornos de grão não é maior que 2 µm.
